We can't keep the cc decoder serialized with video decoder.
If the decoding delay between packetizer and video decoder is bigger
than caching (for example when using multi threaded decoder), we will
be too late for the next picture display while we wait for the right
rendering time for the CC.

See OpenDML spec.

Current RIFF header builder was working with static sizes and
was unable to handle extra metadata.

This will also save more than 9.5KB on most files.

information from the decoder. Use this to pass proper aspect information with
the pictures.
